The crash functions dblock, linkblk, mblock, queue, and stream take an optional table entry argument or address that is
the address of the data structure. The strstat command
gives information about STREAMS event cells and linkblks in addition to message blocks, data blocks, queues, and streams.
On the output report, the CONFIG column represents the
number of structures currently configured. It may change because resources
are allocated as needed.

adb Command

adb is an interactive general-purpose debugger. It can be used
to examine files and provides a controlled environment for the execution of
programs. It has no support built in for any STREAMS functionality.

Note –

adb has reached EOL and is not supported in
the Solaris 9 operating environment. For information about how to transition
from adb to mdb, see the Solaris Modular Debugger Guide.

kadb Command

kadb(1M)
is an interactive debugger
with a user interface similar to adb(1), but it runs in the same virtual address
space as the program begin debugged. It also has no specific STREAMS support.
